of a heavenly being as an adversary to humans evolved into the personified evil of "a being with agency" called the Satan 18 times in Job 1–2 and Zechariah 3. Both Hebrew and Greek have definite articles that are used to differentiate between common and proper nouns, but they are used in opposite ways: in Hebrew, the article designates a common noun, whereas in Greek, the article signals an individual's name (a proper noun). For example, in the Hebrew book of Job, one of the angels is referred to as a satan, "an adversary", but in the Greek Septuagint, which was used by the early Christians, whenever "the Satan" () appears with a definite article, it specifically refers to the individual known as the heavenly accuser whose personal name is Satan. In some cases it is unclear which is intended. Henry A. Kelly says that "almost all modern translators and interpreters" of 1 Chronicles 21:1 (in which satan occurs without the definite article) agree the verse contains "the proper name of a specific being appointed to the office of adversary". Thomas Farrar writes that "In all three cases, satan was translated in the Septuagint as diabolos, and in the case of Job and Zechariah, with ho diabolos (the accuser; the slanderer). In all three of these passages there is general agreement among Old Testament scholars that the referent of the word satan is an angelic being". In the early rabbinic literature, Satan is never referred to as "the Evil one, the Enemy, belial, Mastema or Beelzebul". No Talmudic source depicts Satan as a rebel against God or as a fallen angel or predicts his end. Ancient Jewish text depicts Satan as an agent of God, a spy, a stool-pigeon, a prosecutor of mankind and even a hangman. He descends to earth to test men's virtue and lead them astray, then rises to Heaven to accuse them. In the Book of Job, Job is a righteous man favored by God. Job 1:6–8 describes the "sons of God" () presenting themselves before God. "Sons of God" is a description of 'angels' as supernatural heavenly beings, "ministers of Yahweh, able under His direction to intervene in the affairs of men, enjoying a closer union with Yahweh than is the lot of men.
